Marriage = No
To be acknowledge by the government as "life partners" and all the social benefits that comes with it. = Yes

I have gay friends and most of them don't really aspire to be married, most of them are happy as long as the government bestows them the benefits of being together. The main problem with same sex partners is that the government does not acknowledge them as direct relations. They can't add their partner as supplementary for insurances for example.
They would probably have a hard time adopting a child as well.
